There’s no point in any runway longer than 800m. I’m not a fan of top and both sides. Planes always seem to find the long way. I like 7 on top 4 arriving, 3 deparing, 2-3 on the side arriving with all planes flowing in the same direction. I did find that became more difficult if I shifted the concourse direction to left-right instead up up and down… fun to experiment though. the above plan was with 81 medium gates, no GA

The current airport (slightly modified save file) is 108 gates I think… but it seems to die on loading structures… that one is the new left to right concourses and it’ll probably dump everything I thought I knew on its head.

They can actually. It’s a topic of conversation in the past for sure the airplanes waiting lots of time for other aircraft a long ways away. I actually do a whole thing on it entitled “Can we please do something about this”… It’ll happen in time.
